EXHIBITING 0R DISPLAYING MACHINE.

Application filed. December 11, 1913. Serial No. 805,918.

To all whom it may concern:

Be it known that I, 01.10 B. Yaw, citizen of the United States, andresident of Arlington, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Exhibiting orDisplaying Machines, of which the following is a specification.

My present invention relates tomachines, devices or apparatus forchangeably exhibiting or displaying information, merchan dise, etc, andthe main object of the invention is to provide new and improved devicesof the character specified.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, combinations of devices andarrangements of parts hereinafter described and particularly pointed outin the claims.

The preferred form of my invention is illustrated in the accompanyingdrawings, wherein- Figure 1 is a fragmentary side elevation of themachine, the view showing the casing for the machine proper in verticalsection. Figs. 2 and 3 are detail views of parts of the machine. Fig. 4is a fragmentary rear elevation of the machine. Fig. 5 is a fragmentarydetail view of certain parts shown in Fig. 4: drawn on a larger scale.Fig. 6 is a fragmentary side elevation, partly in section, of the 'upperpart of the machine, the view being drawn to a larger scale than Fig. 1.Fig. 7 is a fragmentary horizontal sectional View taken on a planeindicated by the dotted line 50-00 in Fig. 6 and looking downward.- Fig.8 is a perspective view of a reciproeatory display receiving device orplatform. Fig. 9 is an inner face view of one side of the series oftrack-ways or run-ways which define the path followed by the displays orexhibits in their passage through the machine. Fig; 10 is a horizontalsectional view taken on a. plane indicated by the dotted line y-ay inFig. 9 and looking downward. Fig.11 is a horizontal sectional view takenon a plane indicated by the dotted line z-2 in Fig. 9 and lookingdownward.

As shown in Fig. 1 of the drawings, the machine is inclosed or housed ina covering or casing l which screens or covers it from the spectator andis detachably securedto the base 3 of the machine. The front wall 4. ofthe casing is provided with a display Specification of Letters Patent.Patented API. 18, 1916- opening 5 through which the displays or I Iexhibits may be seen. The casing is preferably open at the rear toafford ready access to the machine proper.

The supporting frame of the machine comprises the base 3 which may be ofwood and which supports an open or skeletonized rectangular frameworkcomprising four up rights or posts 6 rising fro-m the base, these postsbeing preferably of angled metal, their cross section beingshown inFigs. 10 and 11. At thetop the posts are connected by a rectangularframe or top plate 7 which completes the supporting frame, saidtop-plate being screwed or otherwise suitably secured in place. If founddesirable the supporting 7 frame may be strengthened or braced as bydiagonal cross rods 7 Two of these are shown in Fig. 4: connected byscrews tothe upper portions of the two rear posts and supplemented by ahorizontal cross rod 7 The lower portions of the two front posts may beconnected by similar cross rods or braces.

Rising from the base are brackets 8 on which is mounted an electricmotor or'other source of power?) (Figs. 1 and 4). The motor has a shaft10 from which power is transmitted to the display controlling devices,said shaft constituting a driving or power shaft for the machine. To theshaft 10 is fixed near one end a sprocket wheel 11. A counter shaft 12takes bearings in the brackets 8, said shaft being arranged parallelwith the shaft 10 and having secured to itav larger sprocket wheel 13which is connected with the sprocket wheel 11 by a belt or sprocketchain 1 l. At its opposite or outer end the shaft 12 carries a smallsprocket wheel'15 which is connected by a sprocket chain 16 with asprocket wheel 17 v the pairs of bearing brackets 19 and 21 arepreferably adjustable on their supports so as to afford adjustment ofthe shafts 18 and 20 relative to each other. Said shafts carry each apair of sprocket wheels 22, the corresponding members of each pair beingconnected by sprocket chains 23, these chains constituting parallelendless belts or devices on which are mounted the lifting or engagingdevices which, together with the endless belts constitute an elevator ordelivery carrier for the displays. Said devices comprise a transverserod or shaft 24 which extends crosswise from one chain 23 to the otherand is supported near its ends thereon. The end portions of said shaftare reduced in diameter as indicated at 24 and project outward throughtheir bearings in the chains. Secured to said end portions outside thechains as by set screws 25, as best appears from 5, are engaging devicesor hook members 26, the body portions whereof are at right angles to theshaft 24, said body portions terminating at their free ends in hooksproper 27. Bent outwardly at right angles from the body portions arefingers 2S. Arranged on the, reduced ends 24" between the hook membersand the associate sprocket chains are washers 29. The set screws 25 areset so as slightly to clamp the sprocket chains between said washers andthe shoulders formed on the shaft 24 by the reduced ends 24 thus causingsufficient friction toprevent free rotation of said shaft and the hookmembers thereon and so as to hold the hook members in positions,rotatively considered, to which they may be brought or adjusted bycooperating devices or guide ways. Said guide ways in the presentinstance are constituted by the rear faces of the rear posts 6 and bybars or straps 30 which are secured to said posts by screws 31 (Figs. 6and 9). Said screws pass through washers 32 which are interposed betweenthe posts and the straps 30, thus providing narrow passages or slot ways33 through which the associate fingers 28 move upward. The lower end ofeach strap 30 is flared as indicated at 34 so as to provide mouths orpockets to insure engagement of the fingers 28 as they start to moveupward at the forward side of the chains 23. It will be understood thatthe power is communicated from the motor 9 to the sprocket wheel 17 andthe shaft 18 so as to turn said shaft in the direction of the arrowplaced above it in Fig. 1, with the result that the forward sides of thechains move upward and the rear sides of said chainsmove downward asindicated by the arrows in Fig. 6. As the forward sides of the chainsmove upward carrying with them the hook members 26, the-hooks 27 will bemaintained substantially horizontal by the engagement of the fingers 28with the slots 33. Thus controlled the hooks will engage and carryupward or elevate the display ele ments from a lower support ortrack-way to an upper support or track-way that is ar ranged above thelower track-way, these supports being hereinafter described.

The preferred construction of the display elements may best beunderstood from Figs. 4, 6 and 7. Each comprises a rectangular frame orholder consisting of two long parallel sides 35 and twoshorterconnecting parallel sides 36, the long sides being horizontally disposedwhen the display element is in the machine and the short sides beingvertical. Diagonal corner pieces 35 may be provided to strengthen theframe and make it more rigid. The side pieces composing the rectangularframe are preferably of angular metal, thus providing a shallowskeletonized trough which is adapted to receive a card or the like. Inthe present instance a card 37 is provided showing an advertise ment onits face. Obviously, however, other exhibits such as samples orspecimens of textiles or other merchandise may be substituted. This card37 or other exhibit is detachably maintained in place by a pair ofspring clips 38 which are secured by screws 39. to the top of the frameand extend downward behind the card, pressing it forward against theinner face of the frame. A pin 40 projecting upward from the bottom ofthe framev may assist in maintaining the card in. place. Arranged withinand near the top of the frame and bearing in the side pieces 36 is ashaft 41 whose ends project outward beyond the sides of the frame andhave fixed to them small wheels or rollers 42. The shaft and the wheelsare rigid but may turn freely on the frame in which the shaft rotatablybears, the construction promoting even and regular movement of thedisplay along its track-ways. Shoulders 43 on the wheels prevent undueendwise displacement of the shaft.

l/Vhile I have described the form of display element which is preferred,it is to be understood that any other suitable construction may beemployed and that the thing to be exhibited may be detachably mounted onthe frame or other holder or may in itself alone constitute the displayelement. By the terms display element, display or exhibit, ashereinafter used in the claims, is to be understood anything capable ofexhibition or display.

The displays are adapted to follow a path through the machine which isdefined by a series of track-ways as illustrated in Figs. 1, 3, 6. 7 and9. These track-ways comprise two which are parallel and verticallylocated respectively at the front and rear of the main frame and twoothers which are oppositely inclined and connect the vertical track-waysat the top and bottom. Each track-way comprises two parts or elements atopposite sides of the main frame. The lower track-way or supportinclines from the front to the rear and comprises at each side of themachine an angled bar 44 one part of which is in a vertical plane thatsubstantially coincides with the outer face of the main frame and theother part of which is at right angles. The last described part,indicated at 44 provides with its associate part at the opposite side ofthe machine a track or support on which the rollers 42 of the displaysrun. The vertical portions of the members 44 terminate substantiallyflush with the inner edges of the front and rear posts 6 to which themembers 44 are secured by angular straps 45 that are fastened by screws46. The parts 44, however are extended, as best appears from Fig. 9,across substantially the whole width of the posts 6 at the insidesthereof. The rear vertical track-way is formed at each side in part bythe rear posts 6 and in part by a Vertical angled bar 47 secured nearits lower end to the inner face of the post by a screw 48 andcotiperating nut 49. The bar 47 has a portion 47 which is parallel withone wall of the associate rear posts and provides therewith a groove orway 50. Se cured to the inner face of the part 47 is a strip or bead 51best shown in Fig. 11 which prevents the wheels 42 from accidentallybeing withdrawn from the groove after they 7 once enter the same fromthe bottom. It

will be observed that the bar 47 terminates sufliciently far above therear extension of the track portion 44 to permit the rearward passage ofthe rollers 42. The upper track-way is inclined from the rear, forward,oppositely from the lower track-way just described, said upper track-waybeing likewise composed of angled bars or pieces 52 which connect thefront and rear posts and are secured in place by angular straps 58 thatare fastened by screws 54. The

track portion proper 52 of each bar 52 is bent downward at the rear asindicated at 52 .At the front said portion 52 is extended slightlyforward of the rear edge of the posts, leaving a space between theforward end of the part 52 and the front wall of the associate post.Each bar 47 is adapted to turn on its screw 48 as an axis but is limitedin its forward movement by the end portion 52 of the associate bar 52.The front vertical track-way or drop-way comprises two parts and isformed at each side by the front wall of the front post 6 and by atriangular plate of wood or the like 55. This triangular plate underliesthe associate track 52 and is secured thereto by wood screws 56. A strap57 near the lower end of said plate is fastened in place by screws 58and serves to secure the plate to the post near the bottom of theformer. As best appears from Fig. 10 the front vertical face of theplate 55 cotiperates with the-front wall of the associate post to form agroove 59. Fixed to the inner face of the plate 55 by screws 60 is anarrow metal strip or plate 61. This strip through the greater part ofits length is flush with the front face of the plate but near its lowerend is extended forward partly across the groove as indicated at 61 Thepurpose of this construction will be hereinafter explained. The plate 55and strip 61 terminate far enough above the forward extension of theportion 44 to permit free movement of the rollers 42 downward throughthe passage or dropa way formed by the grooves 59 and thence rearwardover the downwardly inclined track-way formed by the parts 44. a

The series of track-ways above described provide a course which isfollowed by each of the set or series of displays. While the number ofdisplays may vary, of course, as found desirable, some twenty-four areshown in the present instance, these being about equally divided betweenthe lower track-way and the upper track-way. Considering those supportedon the lower trackway, it will be understood that owing to the force ofgravity they tend to run down toward the rear, the rearmost one beingarrested by the rear walls of the posts 6. In thisposition the rearmostdisplay is adapted to be picked up by the hooks 27 of the elevatorwhich, owing to the movement of the chain 23, will engage with the shaft41 of said display and will lift said display upward through or alongthe rear vertical track-way. As the display nears the top the roller 42at each side will engage with a transfer device which, as bestillustrated in Fig. 3, comprises abent lever 62 pivoted at 63 on abracket 64 secured to the rear posts. A coiled spring 65'seated in adepression in said bracket cotiperates with the tail of said lever toforce its upper end forward, with the result that when the roller 42contacts with said lever said roller will be forced against the wall 47by the pressure of the spring 65 and when the top of said wall isreached the rollers 42 will be forced by the spring pressed levers ortransfer devices 62 forward on to the tracks 52 of the upper supportwhereupon the display under the force of gravity will run down the trackuntil arrested by the rearmost of the plurality of displays on theupper-support.

Turning now to the foremost one of the displays on the upper support,this is prevented from dropping downward in the drop-way comprising thegrooves 59 and is maintained opposite the display opening 5 for theobservation of the spectator by reciprocatory restraining devices whichare automatically actuated and controlled from the motor 9 throughconnections with the upper shaft 20. Said connections comprise,asillustrated'in Figs. 1 and 4 to 7 a pinion 86 fixed to the outerright-hand end of said shaft, said pinion meshing with a large spur gear67 that is fixed to the outer right-hand end of a shaft 68 that takesbearings in brackets 69 fixed to the rear posts 6. The gear 67 isprovided with spokes and to one of these spokes is pivotally connectedat 70 a forwardly extending link 71. At its front end said link ispivotally connected at 72 to a crank arm 73 fast on the outer right-handend of a rock shaft 74 that may bear in the front posts 6. Mounted onsaid shaft are disks 7 5 provided with hubs 7 6 that receive set screws7 7 by which the disks are secured to the rock shaft 74. These disks 7 5are spaced apart on the rock shaft so as to cooperate with the tops ofthe displays near their ends. Each disk is notched as indicated at 78.The rock shaft 7 at and disks 75 are comprised in the restrainingdevices. With the parts as in Fig. 6 it will be understood that theforward display is restrained or held by engagement with the forwardsides of the notches 78. As the motor driven gear 67 continues to turnin the direction of the arrow (Fig. 6) the link 71 will oper ate to turnthe crank arm 73 rearward, causing the disks 75 to turn in the directionof the said arrow, thus permitting the display to move forward under thedirect influence of gravity and the pressure of the displays behind.This movement will continue until the rollers 42 of the forward displayclear the track faces 52 when the display will be free to move downwardin the vertical dropway as will be understood from Fig. 2. By the timethis occurs, however, the face of the disk in rear of the notch 78 hasmoved down into the path of the next succeeding display which is therebyheld on the upper support and opposite the display opening while thereleased or foremost display is moving downward in the drop-way. Theclips 38 have the additional function of slightly separating thedisplays as will be understood from Fig. 7 so that the restrainingdevices may carry out readily and without obstruction their combinedfunctions of releasing one display and holding or detaining the nextsucceeding display. It will be understood that when the spur gear 67 hasturned far enough to cause the link 71 to begin to move forward andreturn the crank arm 73 toward the front, the disks will turn oppositelyuntil the notches 78 are brought opposite the foremost display on thesupport which will then advance until arrested by the forward side ofthe notches 78, whereupon the operations above described will berepeated, said display being released and permitted to descend in thedrop-way in its turn. The parts are so adjusted and timed that for eachdisplay released at the front of the upper support a display will beelevated. at the rear and added to the plurality on the upper support asdescribed. As the group of displays on the upper support advance towardthe front they will be accurately centered by the plates 55, the rearedges of which are beveled as indicated at 55 to provide a flaringmouth. Also should one of the disks 75 for any reason release theforemost display at one side before the other disk releases it at theopposite side, the

consequent tendency of the display to skew and possibly to wedge in thedrop-way will be prevented by the extended portions 61 of the strips 61which extend over the grooves in the drop-way far enough to pre vent thesides of the display frame from entering said grooves.

In order to prevent unnecessary jarring and possible injury of thedisplays and the tracks and controlling devices therefor, the displays,instead of being permitted to drop freely in the drop-way, are receivedon a receiving device or reciprocatory platform which is connected withthe motor 9 so as to move up and down in the plane of the drop-way andis so timed that it reaches the upper limit of its movement contiguousto the bottom of the display just as the top of said display is releasedby the restraining devices, said platform or receiving device thereaftermoving downward and supporting the display which, through the action ofgravity, follows it until the rollers engage the forwardly extendingportion of the track elements 44 whereupon the dis play will run on thelower track-way until arrested by the displays supported thereon at thetime. The receiving device or movable platform with the actuating mechanism or devices therefor is illustrated in Figs. 1, 6 and S. Saidplatform comprises a vertical body portion 79 having a shelf 80 benthorizontally rearward from its top, the.

end portions of said shelf being bent upward so as to form inclines 81,the purpose of which is to urge the supported display forward againstthe-front side of the dropway and prevent said display from being jarredoff rearward behind the platform. The outer ends of the body portion 79are bent rearward forming ears 82 just outside the front posts. 6. Theseposts are received in the spaces (numbered 83 in Fig. 8) between saidears and the ends of the shelf 80, and thereby serve as guides for theplatform during its up and down movement. Additional guides comprisevertical guide arms or straps 84: suitably secured to the front posts 6.These straps are spaced away from the posts by washers 85, the platformbeing loosely confined between the posts and the straps. The platform isadapted to be reciprocated up and down automatically by the motor devicethrough connections comprising a pinion or small gear wheel 86 which hasa fixed pivot 87 on the righttlz ea hand rear post 6, said pinionmeshing with the spur gear 67 (Figs. 1, 4:, 6, 7). 1 Rigid with the gearwheel 86 is a crank arm 88, to the outer end of which is pivotallyconnected at 89 a downwardly extending link 90. The lower end of saidlink is pivotally connected at 91 to a crank arm 92 fixed to theright-hand end of a rock shaft 93 and projecting forward therefrom. Saidrock shaft takes bearings in angular brackets 9i screwed to the rearposts 6, and has fixed to its left-hand end a crank'arm 95 correspondingto the crank arm 92. Links 96 pivotally connected to the free ends ofsaid crank arms 92 and 95 extend upward therefrom and are pivoted at 97to the ears 82 of the platform. Through the described connections theplatform is given a recipro-.

catory vertical movement. In the present instance a plurality of thesemovements occur idly between successive releases of dis plays, but ashas been stated the timing is such that the platform is brought to theupper limit of its movement every time a display is released by thereleasing devices at thetop of the drop-way. Preferably counterbalancingsprings 98 surround the rock shaft 93 near its ends and are anchored attheir outer ends to the brackets 94, the inner ends of said springsbeing secured in collars 99 on said rock shaft. These springs 98 tend tolift the crank arms 92 and 95 with the platform and connected parts,thus reducing the work of the motor in raising the parts.

After what has been said it is thought to be unnecessary further toexplain the operation of the mechanism, but certain of its features maybe referred to. The number of displays or exhibits may be increased ordecreased as found/desirable without affecting the smoothness andcertainty of operation of the display controlling mechanism. Preferablyabout half of the displays are arranged on the lower support and half onthe upper su port, the elevator, delivery carrier or shi ter taking thedisplays one at a time from the rear of the group on the lower supportand adding them at the rear of the group on the upper support, while theother members of the display controlling and'shifting mechanism, viz.,the restraining devices and the platform, operate concurrently to takethe displays one at a time from the front of the set on the uppersupport and deliver'them at the front of the group on the lower support.When the displays successively reach the front of the group on the uppersupport they are detained for an appreciable time opposite the displayopening in the casing. This time, of course, may be varied either by thespeed of the motor or by changing the proportion and adjustment of theparts. In the present (instance the time that the display is heldopposite the display opening is something like eight or ten seconds butas stated this immediately, and at once the display open:

ing is occupied by the next succeeding display, no time being lost, withthe result that at no period is the display openin'gempty or unoccupiedas in prior constructions, nor

is there an appreciable period during which one display is graduallydisappearing and the other is coming into view when the display openingispartly filled by onedi'splay and partly by the other.

Various changesv may be made without departing from my invention.
